Sensor web simulation investigates technique to improve prediction of pollution across the globe

...concentration of one particular pollutant - carbon monoxide (CO). "The sensor web behaves as a search-and-rescue team," said Principal Investigator Stephen Talabac, lead technologist with the Science Data Systems Branch at NASA's Goddard Space Flight Center, Greenbelt, Md. "Each sensor collects data as part ...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality

... formaldehyde, methane, sulphur dioxide and carbon monoxide and dioxide," Burrows remembers. "Back when we were starting out, many people thought it would be impossible to get any useful results out of the troposphere. There are many important issues to deal with, such as cloud cover and the highly variable r...

Poison + water = hydrogen. New microbial genome shows how

...growing microbes that can convert water and carbon monoxide to hydrogen," remarks TIGR evolutionary biologist ... C. hydrogenoformans grows more rapidly on carbon monoxide than other species: The bug boasts at least five different forms of a protein machine, dubbed carbon...

Blood test predicts success of quitting smoking using the nicotine patch

...asal spray for eight weeks. Measurements of carbon monoxide levels in exhaled air identified those who were not smoking at the eight-week and six-month intervals following the quit date. Study participants also provided information on level of cravings for cigarettes one week after their quit date. "Using t...

NASA study: Alaskan fires affected Houston air quality in 2004

...l Ozone Mapping Spectrometer satellite, and carbon monoxide data from the Atmospheric Infrared Sounder on the Aqua spacecraft. They tracked an air mass from the region of forest fires in western Canada and eastern Alaska on July 12-13, 2004, and followed it as it traveled across Canada, through the mid-wester...

Therapeutic role found for carbon monoxide

U of M researchers invent 'flashy' new process to turn soy oil, glucose into hydrogen

...ep and turns oil straight into hydrogen and carbon monoxide gases by heating it to about 1,000 degrees C. About 70 percent of the hydrogen in the oil is converted to hydrogen gas. Similarly, using a nearly saturated solution of glucose in water, the process heats the sugar so fast that it, too, breaks up into...

New biofuels process promises to meet all US transportation needs

...ess that "gasifies" it into carbon dioxide, carbon monoxide and hydrogen. Then those constituents are turned into a liquid fuel with other processes. In the H2CAR concept, hydrogen would be harvested by splitting water molecules, possibly with a well-known method called electrolysis. Then the hydrogen woul...

Progress toward artificial photosynthesis?

...H group). The by-product of the reaction is carbon monoxide (CO), which can be used directly for chemical syntheses. From a purely formal point of view, this reaction cleaves the CO2 into an oxygen diradical and CO. However, like photosynthesis, the reaction seems to occur by way of carbamates: In the firs...
